10 Best Bicycle Helmets 2025 in the United States

The Giro Fixture II MIPS helmet is designed to fit a wide range of head sizes, making it suitable for men, women, and kids thanks to its universal adjustable sizing. This feature ensures most users can achieve a comfortable and secure fit right out of the box. Comfort is enhanced by the helmet's relatively light weight of just 10 ounces, which helps reduce neck strain during longer rides.

Ventilation is a strong point with 18 Wind Tunnel vents that promote good airflow to keep your head cool on warm days. Safety is a priority with the inclusion of the MIPS (Multi-Directional Impact Protection System), which helps reduce rotational forces during impacts—a valuable addition for mountain biking where crashes can be unpredictable. The helmet's construction combines a tough polycarbonate outer shell with in-molding technology, adding durability without excessive bulk.

The Giro Fixture II MIPS serves as a reliable choice for casual riders and those seeking solid protection and comfort in a versatile helmet.

The SMITH Signal Cycling Helmet is a versatile option for both daily commutes and long road rides. One of its notable strengths is its fit.

On the downside, while the helmet is highly adjustable and comfortable, it may not fit all head shapes perfectly, so trying it on before purchase is advisable. Lastly, the black color option is sleek, but it might not be the most visible choice for those who ride in low-light conditions, although it does give a stylish appearance.
